RUOLO DI ENZIMI PROTEOLITICI NELLA NEOANGIOGENESI TUMORALE. CROSS-TALK TRA CELLULE ENDOTELIALI, TUMORALI E MATRICE EXTRACELLULARE

Ruolo di enzimi proteolitici nella neoangiogenesi tumorale. “Cross-talk” tra cellule endoteliali, tumorali e matrice extracellulare. S. Saladino e G. Ghersi Dipartimento di Scienze e Tecnologie Biologiche, Chimiche e Farmaceutiche (STEBICEF), Università di Palermo, Viale delle Scienze, edificio 16, Palermo-Italia. silvia.saladino@unipa.it L’angiogenesi è un fenomeno complesso che consiste nella creazione di nuovi vasi sanguigni a partire da quelli pre-esistenti (Folkman J, 1992). Tappa critica di questo processo multifasico è il rimodellamento dell’ECM, ad opera di enzimi proteolitici quali metalloproteasi, sistema attivatore del plasminogeno (PA)-plasmina, serino-proteasi transmembranarie …

Tissue Engineering Biopolymers

Tissue engineering has always been a multidisciplinary research area focused on tissue regeneration and restoration of organs function, through implantation of cells or tissues growing outside the body. According to increase in knowledge of the interactions between living organisms and biomaterials, development and diversification of biocompatible devices has brought the world of medicine to what has been the greatest therapeutic revolution of our times. The main challenge of biomaterials is not only related to "tolerance-biocompatibility" by the body but also in its functionality. A biomaterial must be able to positively interact with tissues and exercise those functions for which it was d…
